The Effect of Household Wealth on Fertiliser Use in the Presence of Uncertainty

Previous studies of wealth effect on fertiliser use have produced mixed results on the direction of the impact. Our article looks at this issue from a different perspective by considering the presence of doubts, such as about the true content or general effectiveness of fertiliser. We show theoretically that there could be different responses between the high-wealth and low-wealth farmers. We analyse also the wealth effect empirically using household panel data from the Hebei province of China. The results indicate that the direction of wealth effect does indeed change across the different levels of farmers’ wealth.     

The Economic Constitution of the European Community: From 'Rome' to 'Maastricht'

Abstract: The present paper analyses, from an economic point of view, the changes in the economic constitution of the European Community since its foundation in 1958. In order to identify the various changes, we start by developing an economic frame of reference. Our proposition is that the constitution of the European Community (EC) came closest to this frame of reference: an economic constitution for a market system. In the subsequent parts, we try to show that the process of European integration was largely based on the introduction of non-market elements. Our final argument will be that as far as the economic constitution is concerned, the Treaty on European Union (TEU) is dominated by traits which are Characteristic of modern welfare states.     

Problems of assessing sibship probabilities by means of genetic analysis

Nowadays, kinship studies based only on STR analysis are a very common practice. Apart from regular paternity cases, there is a rising number of cases in which the type of sibship between two persons has to be determined. Very often the parents or further relatives are unavailable for testing, so that the probability e. g. for a half-sibship has to be calculated as a deficiency situation. 50 unrelated persons (Group 1), 50 full siblings (Group 2), and 50 half-siblings (Group 3) were genotyped using the 15 STRs comprised by the AmpFlSTR Identifiler multiplex PCR-kit to investigate the reliability of common statistics programs and the indicative value of the calculated probabilities. Using a commercially available statistics program, we calculated probabilities for the following hypotheses: 1. The persons investigated are full siblings; 2. the persons investigated are half-siblings; 3. the persons investigated are unrelated. After STR analysis, half-sibling probabilities between 0.03 %-97.56% for group 1, between 0.01%-78.46% for group 2, and between 24.28%-90.18% for group 3 were calculated. In addition, the authors present two complicated deficiency cases which could be resolved only by extensive DNA typing using X- and Y-chromosomal loci, respectively, as well as the investigation of further relatives. The results of this study suggest that typing of autosomal STRs alone is no sufficient tool for resolving cases of possible half-sibship, even if probabilities of more than 90.0% are obtained. Due to the results of our study we suggest the implementation of mandatory standards for the investigation and interpretation of complicated kinship cases.     

Evaluation of a novel tagging and tissue preservation system for potential use in forensic sample collection

The authors describe a new, easy-to-use barcode-based tissue collection, preservation and body tracking system, which might prove instrumental in the containment of mass fatalities such as aircraft accidents, war related accidents, environmental disasters (e.g. earthquakes, hurricanes, and floods) terrorist bombings or mass murders.     

Pathogenesis of conjunctival petechiae

Conjunctival petechiae from 15 cases (cause of death: different natural and unnatural) were analysed using confocal laser scanning microscopy (CLSM) in order to visualize the kind of the damage within the vessel wall (diapedesis versus rhexis). The pathomorphological findings with multiple ruptures of vessels appearing to be filled to bursting point define the conjunctival petechiae as a rhexis-haemorrhage.
